    You need to use the correct version of PoweShell and must run it as administrator.  I found the correct version and launched it with run as administrator and it works.

    Hi Dave Similarly I received pnputil as an unknown script. I am using Windows 11 and the Memory Integrity is unable to be turned on as oem60.inf recorded as driver ew_usbenumfilter.sys is the driver blocking memory integrity. The driver is shown as Huwawei.

      You must have c:\windows\system32 in your system path.
